This lesson will give the students an introduction to meiosis. They will have to use prior knowledge of mitosis and replication to understand meiosis.
WHAT WILL STUDENTS HAVE ALREADY DONE? WHAT MAIN IDEAS WILL THEY ADDRESS IN THIS LESSON? WHAT STRATEGIES/ACTIVITIES WILL YOU USE?
Learning Performances
Learning performances illustrate how students should use the scientific content and practices in tasks and reflect the reasoning tasks we want students to be able to do with scientific knowledge.

This is a one period introduction that should take about 40 minutes
Instructional Sequence
Introducing the lesson
I will start with a starting activity on the board for the students to do right form the start. They will be working in groups to think and pull ideas from each other. They will have to put their group ideas on the board and explain.
WHAT IS THE ACTIVITY? WHAT WILL YOU SAY? WHAT WILL YOU DO? HOW WILL YOU RELATE THIS OPENING ACTIVITY TO THE IDEAS OF THE LESSON?
Instructional Activities
I will have an activity on the board that will bring out their prior knowledge. They will have to draw out and explain mitosis. This is information that I have already taught them and should know. I will go over all the steps with the students to make sure they still know this information. After this I will explain in words what meiosis is.
WHY WOULD I CARE ABOUT THIS? WHAT QUESTION ARE WE TRYING TO ANSWER?
I will state that is is just like going through mitosis twice and that it is used in/for sexual reproduction. Then I shall break the students into groups ware they will have to think about what i had just taught them and draw out all the steps. They will have to think about how mitosis and meiosis are different and how they are similar and what each is used for.
WHY ARE MITOSIS AND MEIOSIS DIFFERENT?
Since meiosis is used in passing of genetic traits and that half come from your mother and half comes from your father then at the end of the second division there should be half the number of chromosomes at the last step. Each group will have to draw their ideas on the board and explain their though process to the class. I can have the students vote on which group they think is correct and then I will explain the whole process and go through and explain on any misconceptions that the students had come up with during their thinking process. When I am done I will give a hand out going through all the steps.
WHAT WILL YOU SAY? WHAT WILL YOU SHOW THEM. I LIKE THE IDEA OF THEM PARTICIPATING ON THE BOARD. HOW WILL YOU INCORPORATE THEIR WORK INTO WHAT YOU SAY? HOW WILL YOU INTERPRET THEIR WORK?
Concluding the Lesson
I will reinforce the purpose with a handout where they will be able to see the proper steps and what goes on. I will explain that through meiosis this is how genes and traits are passed on from generation to generation through sexual reproduction. The main idea is to introduce meiosis to the students and have them use prior knowledge to understand the concept.
WHAT DOES IT MEAN TO "INTRODUCE" A CONCEPT? WHAT DO YOU WANT STUDENTS TO BE ABLE TO DO WITH THEIR KNOWLEDGE BY THE END OF THE LESSON?
Assessing Student Understanding
They will have a homework assignment that will have to do with meiosis that will be gone over in detail to assure that all students understand the concept at hand. Cautions There are no precautions that need to be taken in this lesson.
